I would feel bad if that's actually someone I should know but I'm not going to feel bad because who texts someone saying "you know who I am" if you're a normal person and you call someone for a reason you'd state who you were.

don't play games on my phone, I'm the master at games.

Once a girl I knew tried to prank call me so I interrupted her prank to go to the bathroom and made grunting noises and then flushed the toilet, I heard her scream and hang up.
